Fast scrolling on Autostar?

My telescope/Autostar manual states: "Press the Scroll keys to move through the options. Press and hold a Scroll key to move quickly through the options." ..but whenever I press and hold a scroll key (in menus or lists), nothing happens at all. Scrolling through long lists is a pain, having to press the scroll key so many times. This sounds like it would be great if it worked. Does this work on anyone else's Autostar? (Note: I have the Audiostar version of the handbox)
